size: 118mm x 106mm x 49mm Material: Aluminum alloy colour: Black Package Contents: 1 x Audio Isolator Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. The audio isolator provides input interface 3.5mm++XLR+6.5mm, output interface +XLR+6.5mm, and supports multi-connection conversion. The isolation transformer made of permalloy nickel steel sheet material completely isolates the input and output signals. Using Nutrek XLR sockets, you can completely isolate the two systems, reducing noise and ground loop noise. the noise generated when the camera is connected to the audio equipment; the noise generated when the simultaneous interpretation equipment is connected to the mixing console; the noise generated by the laptop connected to the mixing console; the noise generated by the electronic musical instruments connected to the mixing console. Audio Noise Canceling Splitter: Prevent sound attenuation, noise, distribute audio and protect devices. Inconsistent noise transmitted over long distances; noise from devices and device impedance mismatches. It is also suitable for a series of audio equipment systems such as large-scale outdoor performances, fast charging protection, audio engineering, conferences, entertainment venues, exhibitions, etc. It is an essential equipment for audio system cascade.
